Display screen or portion thereof with animated graphical user interface



FIG. 1 is a front view of a first image in a sequence for a display screen or portion thereof with animated graphical user interface, showing our new design;

FIG. 2 is the second image thereof;

FIG. 3 is the third image thereof; and,

FIG. 4 is the fourth image thereof.

The appearance of the animated graphical user interface sequentially transitions between the images shown in FIGS. 1 to 4. The process or period in which one image transitions to another forms no part of the claimed design. The broken lines in the drawings illustrate a display screen and portions of an animated graphical user interface that forms no part of the claimed design. 

CLAIM We claim the ornamental design for a display screen or portion thereof with animated graphical user interface, as shown and described.
